How Crowded Is Jimmy Carter National Historical Park in September?

September runs about 1.7× Jimmy Carter National Historical Park's average month, which makes it a very busy month here — roughly 15% of the park's yearly visitors come in September.

In a typical September the park sees roughly 6,900 recreation visits, based on National Park Service monthly counts from 1988 to 2025.

It is the single busiest month of the year at Jimmy Carter; January, the quietest, runs only about 0.5× the average — a 3-to-1 swing between high and low season.

On our Best Time to Visit score September rates 39/100 ("Poor"), versus the top-rated October at 74/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 85°F and an overnight low around 65°F, with about 4" of precipitation.

That average of about 75°F is a comfortable range for hiking and being outdoors all day.

Because June, July and August together draw about 24% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.2 hours of daylight in September to explore — between the 9.9-hour midwinter low and the 14.1-hour summer high.

Park-wide, 2025 drew 39,101 recreation visits, up 18.4% from 33,031 in 2024.

Across the past decade overall visitation has eased about 40.8%, so September may feel a touch quieter than it once did.
